MOTOR-PLOW.

Specification of Letters Patent.

Patented Oct. 19, 1915.

Application filed October 24, 1914. Serial No. 868,464.

To all whom it may concern.

Be it known that I, ARCHIE J. BLAUVELT, a citizen of the United States, residing at Erin, in the county of Chemung and State of New York, have invented certain new andv A further object is to provide a plurality of pairs of plows arranged for automatic operation and supported by a platform having a shiftable motor thereon and whereby the plow is driven in the desired direction upon the proper positioning of the motor at the desired end of the platform.

A still further object is to provide a motor driven plow capable of plowing two furrows across a field when the motor is at one end of its supporting platform and adapted to plow two other furrows across the field when returning in the opposite direction and at which time the motor is at the opposite end of the platform. For this purpose a sliding motor is provided which without the employment of reversing gears is positionable by mechanical means at either end of the machine platform and adapted to operate and thus propel the device forwardly of whichever end of the platform the motor is positioned. It is also designed so that the operator may adjust all of the mechanism and plow an entire field without leaving the machine platform.

WVith these general objects in view and the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts to be hereinafter more fully described,illustrated in the accompanying drawings, and setforth in the appended claims.

In the drawings forminga part of this application and in which like-designating characters refer to corresponding parts throughout the several views, Figure 1 is a'front elevation of the device'with a por tion of "the elements removed. Fig. 2 is a top plan view of the device. Fig. 3 is a lonview thereof partially broken away, and with parts removed, with the motor centrally positioned. Fig. 4; is a similar view with some of the elements removed and with the motor operatively positioned at one end of the platform. Fig. 5 is an end view of the device with the guiding wheels and their mounting mechanism removed. Fig. 6 is a detail sectional view through the platform showing the wheel adjusting means. Fig. 7 is a detail view enlarged of one of the adjusting means for the plows, a plow being shown in its elevated position by dotted lines, and Fig. 8 is a detail view of the shiftable means for the motor.

Referring more in detail to the drawings, it is broadly designed to provide a platform 10 having a motor 11 of any desired construction mounted thereon and adapted to propel the device in either direction by imparting movement to the traction wheel 12 at one side of the platform, while an adjustable ground wheel 13 of lesser diameter is positioned at the opposite side thereof. The platform 10 adjacent the traction wheel 12 and a similar side wall 15 adjacent the wheel 13. A post 16 positioned upright upon the platform 10 is in spaced relation with respect to the side 14 and the axle of the traction wheel 12 is journaled in the post 16, and a stub post 17 adjacent the walll l. The inner face ofthe traction wheel 12 is provided with a toothed gear wheel 19 in constant mesh with a pinion 20 which is fiXed to a stub shaft 21 ouris provided with a side wall 14 V V naled at the top of the post 16 and upon which stub shaft 21 a driven gear 18 is'also fixed.

The motor 11 is provided with rollers 22 and by means of which it is mounted upon the platform 10 between oppositely positioned parallel guide strips 23. A driving pinion 2 1 of the motor has a sprocket chain 25 passing thereover and also over the said driven gear 18, opposite balance or fly wheels 26 being also provided for the motor shaft 27 By this arrangement, it will be seen that when the motor is positioned at either end of the platform 10 as illustrated in Fig. 4, the chain 25 will be taut thus allowing for a transmission of power from the engine shaft to the traction wheel The motor may be shifted upon the platform 10 to a central position as shown in Figs. 2 and 8 and at which times the chain will be slackened so that the chain 1 will have no connection w'ith the'driving pinion 24 and the traction wheel will be uninfiuenced by the motor. The motor may be placed at the opposite end of the platform from that shown in ig. 4 and the same started in an opposlte dlrection for lmparting an opposite movement tothe device. Pulleys 28 are positioned at the opposite ends ofthe platform 10over which cords- 29 are passed having their inner ends secured as at 30 to opposite points upon the motor 11. The opposite ends of-these cords are attached at diametrically opposite points upon a'diskyp ulleyi 31 positioned beneath the .platformlOand upon the lower end of 7 an upright rod 32 journaled in the said platform and adapted for turning by means .of atop hand wheel 33. The cords 29 may thus be wound upon the turning the wheel 33 andthus pullingthe motor across'the platform '10 for positioning the same-at any point desired. A 'spring latch'34 carried by the journaling' bushing V 35 of the post 32 is adapted to retain the post against rotation at any point in the travelof the motor 11, such as theoperative positions of the motor at the opposite ends of the platform. The smaller ground wheel 13 is journaled ina block 36 through which the wheel axle 37 extends and-is vertically slidable within a bracket 38- being capable of adjustment therein by theoperatform 10 andhave laterally extendingjour- I nals 43 .at their ends adapted for mounting,

thereon small steering .wheels 44 which are capableof lateral movement in the 7 operation. 7 The axles 45 of each of the said wheels 44 are i rods 46 hinged to the-said axles and having provided with steering overlapping ends 47 spaced apart and pro-f .vided" with inwardly positioned'toothedracks 48 in constant mesh with alpinion 49;- Y The pinion 49 has an upright rod15O'secured thereto and journaled in a laterallyextending arm 51 of the side wall 14. A gear 52 rigidly mounted uponthe rod 50 ends of rods 54 which are'journaled in the opposite ends of across arm 55 of the said: arm 51. The inner ends of therods 54 have hand wheels 56 secured thereto which are positioned at points convenient for operation'by the driver of the device upon the seats 57 thereof. It will thus be seen that upon whichever oneof the seats 57, the driver may be positioned, he may by turning the adjacent one of the hand wheels 56 influence the two steering wheels 44 for steering the device in the desired direction. Plow members 58 are positioned at each and are pointed in an opposite direction. Each of the said plows 58 and 59is attached 'by a chain 60 to some convenient portion of the framework of the device and'whereby movement of the device. It being only de pulley 31 upon steering with each other and pointing in the same direction, while similar plows 59 are alternately arranged with respect to theplows58 the plows are directed forwardly upon a sired-to employ: only. one set ofplowsj when moving in 'each direction, the plows are? each end of the platform out of alinementVv n pivoted to the lower ends-of'separate elevat- 3 ing levers 61 and whereby: the r plowsywhich are not desired for use maybe elevated above the ground as illustrated in dotted" lines in Fig. 7. The le 'ers 61 are pivoted to brackets 62 carriedby the framework and I have theirfree ends adapted to be retained by clips 63 also carried by the platform and whereby the levers may be retained in their horizontal positions and with the plows elevated. The hinged frames4l have slight. rear extensions 64which are adapted to engage the top of the platform 10 as illus-' trated at the right-hand end of said platform in Fig. 4, when the motoris positioned at that end thereof, while the similar frame at the oppositeend of the platform will then betilted at an inclination to the platform.
